Speccation of Letters Patent.

Application filed November 28, 1906l Serial No. 345,447.

To all whom t may concern:

l Be it known that I, NELS FREDRIOK MOG LAND, a citizen of the United States, residing at 13 South Ann street, in the county of Oook and State of Illinois, have invented a new and useful Improvement in Binders, of which the following is a specification.

My invention relates particularly to binders in which are employed two flattened tubular bars or binding members in connection with binding-posts, such binders being commonly known as transfer-binders.

My primary obj ect is to provide improved means of covering said bars with leather or fabric and finishing the ends of the bars.

The invention is illustrated in its preferred embodiment in the accompanying drawings, in which- Figure l represents an edge elevational view of a transfer-binder constructed in accordance with my invention Fig. 2, a broken inner view of one of the cover-sections and the clamping-bar or binding member connected therewith, the tip end of the bar being omitted, however; Fig. 3, a similar view with the end tip of the bar inserted and secured; Fig. 4, a broken sectional View taken as indicated at line 4 of Fig. 2; Fig. 5, a broken sectional view -taken as indicated at line 5 of Fig. 2; Fig. 6, a broken sectional view taken as indicated at line 6 of Fig. 3 Fig. 7, a

' broken perspective view illustrating the manner in which the binding-leather is placed with relation to the cover-section and clamping-bar in the first step of applying the binding-leather; Fig. 8, a similar view showing the manner of making the first fold of the binding-leather; Fig. 9, a broken perspective view illustrating the second fold of the binding-leather; Fig. 10, a broken pers ective view showing the third fold of the binding-leather, and Fig. l1 a similar view showing an additional piece of leather applied to the inner surface of the cover-section and that portion of the leather which covers the end of the tubular binding member slitted to receive the end plug or tip shown in Fig. 6.

In the construction shown, A A represent cover-sections having connected with their rear edges flattened tubular clamping-bars or clamping members A2 A3; B, binding-posts carried by the lower clamping-bar and eX- wardly, as indicated at a9 in Fig. 5.

tending through perforations in the upper clamping-bar in the usual manner, and O loose leaves secured in the binder in the usual manner.

The clamping-bars are connected with the cover-sections by portions of binding-leather, affording iieXible hinges a. As illustrated in Fig. 7, a strip of binding-leather a is applied to the outer surface ofthe rear margin ofthe cover-section and to the outer surface of the clamping-bar in Such manner as to leave a portiona2 projecting beyond the lateral edge of the cover-section and beyond the end of the clamping-bar and to leave also a portion a3 projecting in the rear of the clamping-bar. The portion a2 is then folded over and cemented on the inner surface of the cover-section and upon the inner external surface of the clamping-bar in the manner shown in Fig. 8. A corner a4 of the folded leather is then folded in in the manner shown in Fig. 9, and the projecting iiap a3 is then folded in and cemented upon the inner external surface of the clamping-bar in the manner shown in Fig. 10, overlapping the flap a2 in the manner illustrated. Where the bar is somewhat shorter than the width of the cover-section, the leather forming the hinge is struck in in the manner indicated at a5. A strip of thin leather 0.6 is then cemented upon the inner surface of the cover-section, overlapping the flap a2 and the iiap a3, as shown in Fig. 11. The leather is also provided with a slit a7, which is coincident with a plane passing through the center of the flattened tubular bar and through the center of the cover-section. An end plug as, having a fianged head and a reduced body portion conforming in shape to the interior of the bar, is then driven into the bar, thereby turning the leather in- After the plug is driven in a pointed instrument is employed to cut a triangular projection or brad alo from the tubular bar and force the same into the shank of the plug in the manner illustrated in Fig. 6, thereby preventing removal of the plug. The plugs conform in shape to the cross-sectional shape ofthe bars, and the flanged heads are of about the same cross-sectional area as are the bars with their wrappings upon them, so that the iianged head is substantially flush with the external surface ofthe bar after the bar is bound with ICO leather. The end plugs are commonly of aluminium and the tubular bars are of steel,

.so kthat the brad al may be forcedyinto the Shanks of the plugs without difliculty. In

practice the upper clamping-bar contains the locking mechanism for securing said clamping-bar at any desired height upon the binding-posts B. One end plug of the upper clamping-bar is provided, therefore, with a perforation a, which receives the end of thc screw which serves to operate the clamping mechanism. The clamping mechanism may beof any approved construction and is not illustrated, inasmuch as it forms no portion of the present invention. Thebinding-posts B are commonly secured to metallic plugs b, which are located within the lower clampingbar at a suflicient distance from the ends thereof yto enable the end plugs to be inserted.

The foregoing detailed description has been given for clearness of understanding, and no undue limitation is to be understood therefrom.

-What I regardas new, and desire to secure by Letters Patent, is-

1. In a binder, the lcombination with a cover-section and a hollow clamping-bar, of.

binding material applied toand-flexibly connecting the cover-section and clamping-bar,

.a portion of the binding material being folded into the end of the bar, and an end plug for the clamping-bar having a reduced portion entering the end of the bar and securing the binding thereat, for the purpose set forth.

2. In a binder, the combination with a cover-section and a hollow clamping-bar, of fiexible binding material applied to the outer surface of the coveresectionand the outer ex- `ternal surface of the clamping-b ar and having a yflap folded inwardly over the edge of the .cover-section and over the end of the `bar and having a fiap folded forwardly over the rear edge of the bar, and an end plug having a shank entering said bar, the binding material adjacent to the shank of rvsaid plug being forced into said bar, for the purpose set forth.

3. In a binder, the combination `with la cover-section anda `hollow clamping-bar, of binding material applied totheI outer surface of the cover-section and Vthe outer external surface of the clamping-bar and having a flap folded inwardly over the edge of the cover* section and over the end of said bar and havving also a flap folded forwardly over the rear edge ofthe clamping-bar, said flaps being cemented on the inner surface of the cover-section and the inner external surface of ythe clamping-bar, and a plug having a flanged lthe bar having a slit therein, `said 'binding material also havin a flap folded inwardly over the rearedge ofthe bar, a strip of binding material applied to the inner ysu-rface of the cover-section andlthe inner external sun face of the clam ing-bar and overlapping said flaps, an en plug having a shank en-l tered in said bar, the binding-materialbeing forced inwardly thereat and confined lbe'- tween said shank and the interior surfaceof the bar, .and a brad struck inwardly from the metal of the bar and yengaging said shank, for the pur ose set forth.
